"This resolving power" was obviously stated earlier, somewhere before the point where you started copying. With no resolving power specified, there's actually no question, and so no answer.
Answer:
D
Explanation:
The student had displaced their in the class when she left. The phone is what's displaced and student leaving equals distance.
She threw the marshmallow at a speed of around 4.76 m/s.The formula for the horizontal range gives the velocity.
<h3>What is projectile motion?</h3>
The motion of an item hurled or projected into the air, subject only to gravity's acceleration, is known as projectile motion.
The item is known as a projectile, and the course it takes is known as a trajectory. Falling object motion is a simple one-dimensional kind of projectile motion with no horizontal movement.
Given data;
The marshmallow was thrown at a distance of 2 meters
Range,R = 3 m
Initial velocity,u
The angle at which the marshmallow was thrown,θ = 30°
The acceleration due to gravity,g = 9.81 m/s²
The projectile's motion is divided into two parts: horizontal and vertical motion.

Hence, she throws the marshmallow at a speed of 4.76 m/sec.

h, it has the lowest density so it makes sense it is the gas.
I think you could use Bohr model and the Plum Pudding Model
Bohr Model : the one that states atoms consist of positively charged nucleus and orbited by negatively charged electrons
Plum Pudding model : Atom consist of objects made to pieces with positive and negative charges
hope this helps
